Chapter 1: Q18. (page 25)

Find the perimeter of each figure. Round to the nearest tenth.

Short Answer

Expert verified

The perimeter of the given figure is 15.4 inches.

Step by step solution

01

Step 1. Given information.

In the figure, there are two semi-circles with a diameter 3 inches on two sides of the square with side 3 inches.

02

Step 2. Concept used.

The perimeter of a polygon is the sum of the lengths of its sides.

Circumference of a circle with diameter d is given by C=蟺d.

03

Step 3. Calculations.

The circumference of a circle

C=3.14脳3=9.42

The perimeter of the given figure will be equal to the sum of the circumference of the circle and two sides of a square.

P=9.42+3+3=15.42

Rounding off to the nearest tenth, we get,

P=15.4inches

Thus, the perimeter of the figure is 15.4 inches.
